From March thru the October Bangladesh is one big CB. 24hrs a day most days the whole place is covered with them, from bases about 2000ft to well over 50 000ft, incredible to see , and scary. I absolutely hate it when we transit Bangladesh airspace on the way to china or Vietnam and are stuck at 290 or below after a stop in VECC weaving in and out of the storms cells that are within 10 nm of you, and to make it worse the ATC system of Bangladesh must be the worst in the world and they have some real busy airspace at certain times of the day. There is no weather radar also and the metars and tafs and pretty unreliable, its really like bush flying .
I would not take a job flying a ATR or Dash flying in Bangladesh no matter how much someone paid me! Some days you can hear the stress in the voices of the Pilots in those aircraft as they are fighting their way thru the storms, always makes the hairs on my back stand up the thought of what they are witnessing when I hear the radio chatter.
